Which one 11 or 13. it be easier to know
For this case we have the following equation:

Deriving we have:

We match zero:

We clear the value of x:

Then, we substitute the value of x in the equation of the parabola:

Thus, the vertex of the parabola is the ordered pair:
Answer:
The vertice is:
Hello!
You can only add values that have the same terms
4k^4 + 5k^4 = 9k^4
-3k + k = -2k
-8 + 2 = -6
The answer is 9k^4 - 2k - 6
Hope this helps!
Answer:
D: -75 the balloon is descending at a rate of 75ft per minute
Step-by-step explanation:
To find the slope of any graph, take two points on the graph and subtract them y/x so to get this answer is used the points (0,450) and (2,300) and subtracted the y-values over the x-values
450-300=150
0-2=-2
150/-2 = -75
that is the slope and since it is negative and the slope itself is a diagonal line going towards the x-axis you know it’s descending.
Hope this helps :)
